What is your question?

If i try to run tests i get the following error Message:

and if i try to use a specific version with the following command,

"test": " set MONGOMS_VERSION=6.0.4 && jest --runInBand",

i get the message:

Neither me nor my professor have any idea how to fix it, but already tried reinstalling everything.

mongodb-memory-server-*: 6.0.4

such a mongodb-memory-server version does not exist, the last 6.0.x version is 6.0.2, in any case, 6.x is not supported anymore. currently the latest version is 9.2.0.

If i try to run tests i get the following error Message:

did you already try what the error suggests and install the latest vc_redist package?

"test": " set MONGOMS_VERSION=6.0.4 && jest --runInBand",
Error: Download failed for url "https://fastdl.mongodb.org/windows/mongodb-windows-x86_64-6.0.4%20.zip", Details:

something with your set command is likely wrong and adds a extra space to the environment variable (resulting in 6.0.4 ), which should (to my knowledge) not happen, though in the future i guess we can try to trim the input.
i dont know if this will work on windows, but does running MONGOMS_VERSION=6.0.4 jest --runInBand work (instead of your set and && command)?
if that does not work and this is the package.json anyway, try setting it under config, see How to use them in the package.json

Let me try to clarify the situation a little bit:

• We (I helped @Blacedraco) first tried to use the default version, which is 6.0.14, istn't it?
• As this version did not work, we tried different other versions, one of them was 6.0.4. So we do not insist on using 6.0.4, it was just a test.
• mongodb-memory-server-*: 6.0.4 -- That's wrong, we actually use 9.1.8. Must have been a copy-paste-error when creating the issue.
• I would consider the trailing space in the version number a bug, but as @hasezoey already wrote, this could be easily fixed.
• AFAIK "set" is the way do set an environment variable under Windows, isn't it?
• @Blacedraco: Try to run the tests with this script line (with no space before the &&):
  "test": " set MONGOMS_VERSION=6.0.4&& jest --runInBand"
  Maybe you could also try older MongoDB-versions, such as 5.x.
• As far as I understand, vc_redist has already been installed manually. But I'm no windows expert.
• We downloaded some versions manually, unzipped the download, renamed (mondgod-x64-win32-...exe) and moved the exe file to c:\Users{user}.cache\mondodb-binaries. However, MMS did not pick up our manually installed versions, i.e. it tried to download them again (with the space-problem in the URL). I did this trick under macos where it worked. Has the location changed? Hmm... after thinking about it, I would assume that the trailing-space problem sabotaged all our tests.

[Blacedraco]

removing the space before the && didn't change anything in the output neither did changing the specified versions in that command.
Removing the set and && gave me another errormessage as it cant read that command in that constellation

all the default versions can be found at Mongodb Server Versions

AFAIK "set" is the way do set an environment variable under Windows, isn't it?

i dont know, i dont use windows and didnt check for this issue (as there were seemingly more glaring issues), in linux / unix you can just prepend the environment variable if it should only be valid / set for that command.

maybe try to surround the environment variable's string with quotation marks: MONGOMS_VERSION="6.0.4" or the full string "MONGOMS_VERSION=6.0.4".

maybe you are running into this problem on stackoverflow.

Hmm... after thinking about it, I would assume that the trailing-space problem sabotaged all our tests.

it is likely that the full version MMS was searching for was mongodb-x64-win32-6.0.4 .exe as the version gets added without trimming currently (as to my knowledge trailing spaces should never be there), it also never came up as a problem.

as a side note, you can use config option USE_ARCHIVE_NAME_FOR_BINARY_NAME to use the archive name as the binary name instead (though this will make it unable to read the already existing other style binaries).

As far as I understand, vc_redist has already been installed manually. But I'm no windows expert.

i would like to help, but the only error we get is the high exist code (3221225781), which on windows until now always indicated a missing install of vc_redist.

[jpilgrim]

I have to correct myself: The trailing space is a problem of the Windows cmd tool. But as mentioned, there are workarounds, e.g. by defining a variable in package.json or removing the space before the &&.

[Blacedraco]

Changing the version number to an actual existing one an removing the space between the number and the && made it finally work.
The Version that works looks like this : ..MONGOMS_VERSION=4.0.27&&..
thanks to all that suggested solutions and helped with that problem
